Abstract
A kind of pitch motor Opposite side loading experimental rig is related to Wind turbines variable pitch experimental rig, solves that existing variable pitch experimental rig variable pitch limited angle, equipment is heavier, inconvenient, easy the technical issues of causing danger.The utility model includes：The main part being made of wheel hub, pitch variable bearings, variable paddle speed reducer and pitch motor, it is characterised in that：On the outer ring of the pitch variable bearings, by the supporting rack being connect with main part, Opposite side loading pitch motor and retarder is installed, the output gear of retarder is made to be engaged with pitch variable bearings.The Opposite side loading pitch motor passes through Frequency Converter Control.The utility model is tested for wind generating set pitch control, has device simple, light-weight, easy to operate, the advantages of can accurately simulating blade loading conditions.
Description
Technical field
The utility model belongs to technical field of wind power generation, more particularly to a kind of pitch motor Opposite side loading experimental rig.
Background technology
Currently, feather technology has been widely used in Wind turbines, Wind turbines need to carry out after the completion of assembly
Variable pitch is tested, it is therefore an objective to detect the function and reliability of pitch-controlled system.
Common variable pitch experimental rig includes：Main part, hub bracket, load reel and counterweight.Including wheel
The main part of hub, pitch variable bearings, pitch motor is mounted in hub bracket, and load reel is fixed on pitch variable bearings, counterweight
It is lifted on load reel end by steel wire rope.
Existing variable pitch experimental rig has the disadvantage that：Need use higher hub bracket, counterweight it is heavier and test when
It is easy to happen and falls, the load effective rotation angle of reel is limited etc..
Invention content
The shortcomings that the purpose of the utility model is to overcome the prior arts provides a kind of pitch motor Opposite side loading experiment dress
It sets, solves that existing variable pitch experimental rig variable pitch limited angle, equipment is heavier, inconvenient, easy the technical issues of causing danger.
The utility model is achieved through the following technical solutions：
A kind of pitch motor Opposite side loading experimental rig, including：By wheel hub, pitch variable bearings, variable paddle speed reducer and variable pitch electricity
The main part of machine composition, it is characterised in that：On the outer ring of the pitch variable bearings, pass through the support being connect with main part
Frame installs Opposite side loading pitch motor and retarder, the output gear of retarder is made to be engaged with pitch variable bearings.
Further, the Opposite side loading pitch motor passes through Frequency Converter Control.
The utility model compared with prior art, passes through the Opposite side loading of Frequency Converter Control due to being installed on pitch variable bearings
Pitch motor and retarder, the variable pitch experiment of Wind turbines, without hub bracket, load reel and counterweight, therefore, this reality
It is had the following advantages and beneficial effect with novel：
1, variable pitch experimental rig is simple in structure, small, light-weight, easily operated.
2, Opposite side loading pitch motor uses frequency control, can accurately simulate the loading conditions of blade.
3, the effective rotation angle of variable pitch is unrestricted.
The utility model is tested for wind generating set pitch control, has device simple, light-weight, easy to operate, can essence
Really the advantages of simulation blade loading conditions.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of pitch motor Opposite side loading experimental rig；
Fig. 2 is a kind of sectional view of pitch motor Opposite side loading experimental rig.
Wherein：1- Opposite side loadings pitch motor, 2- retarders, 3- supporting racks, 4- pitch motors, 5- variable paddle speed reducers, 6-
Pitch variable bearings, 7- wheel hubs.
Specific implementation mode
Clear, complete description is made to the technical solution of the utility model by embodiment below in conjunction with attached drawing.
As shown in Figure 1, 2, a kind of pitch motor Opposite side loading experimental rig, including：By wheel hub 7, pitch variable bearings 6, variable pitch
The main part that retarder 5 and pitch motor 4 form, it is characterised in that：On the outer ring of the pitch variable bearings 6, by with master
The supporting rack 3 of body portion connection, installation Opposite side loading pitch motor 1 and retarder 2, make output gear and the change of retarder 2
Paddle shaft holds 6 engagements.
The Opposite side loading pitch motor 1 is by Frequency Converter Control, it can be achieved that forward and reverse speed-changing rotation.
The operation principle of the utility model is as follows：
Opposite side loading pitch motor 1 is engaged by the output gear of retarder 2 with pitch variable bearings 6, is provided to pitch variable bearings 6
One opposing torque.After variable pitch on-test, pitch motor 4 drives pitch variable bearings 6 to rotate by variable paddle speed reducer 5, reversely
Load pitch motor 1 prevents pitch variable bearings 6 from rotating by retarder 2, the opposing torque applied by Opposite side loading pitch motor 1
The load for carrying out equivalent blade, the pitch process of Wind turbines is simulated with this.
The spirit and scope that the utility model can in a variety of forms be embodied without departing from the utility model, should manage
Solution, above-described embodiment is not limited to details above-mentioned, and should widely be explained in claim limited range.It should refer to
Go out, for those skilled in the art, without departing from the principle of this utility model, can also make
Variation in several improvement and equivalent scope, such modifications and variations also should be regarded as the scope of protection of the utility model.
